ASU Electronic Theses and Dissertations


This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.

In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.

Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries. For more information or questions about this collection contact or visit the Digital Repository ETD Library Guide or contact the ASU Graduate College at gradformat@asu.edu.


The sun provides Earth with a virtually limitless source of energy capable of sustaining all of humanity's needs. Photosynthetic organisms have exploited this energy for eons. However, efficiently converting solar radiation into a readily available and easily transportable form is complex. New materials with optimized physical, electrochemical, and photophysical properties are at the forefront of organic solar energy conversion research. In the work presented herein, porphyrin and organometallic dyes with widely-varied properties were studied for solar energy applications. In one project, porphyrins and porphyrin-fullerene dyads with aniline-like features were polymerized via electrochemical methods into semiconductive thin films. These were shown …

Nanoporous crystalline oxides with high porosity and large surface areas are promising in catalysis, clean energy technologies and environmental applications all which require efficient chemical reactions at solid-solid, solid-liquid, and/or solid-gas interfaces. Achieving the balance between open porosity and structural stability is an ongoing challenge when synthesizing such porous materials. Increasing porosity while maintaining an open porous network usually comes at the cost of fragility, as seen for example in ultra low density, highly random porous aerogels. It has become increasingly important to develop synthetic techniques that produce materials with these desired properties while utilizing low cost precursors and increasing …
